Objectives and Context

INSPIRE, the European Directive establishing an Infrastructure for Spatial Information in the European
Community, provides a large number of data models. While these cover many core use cases, they often need to
be extended to serve specific organisational needs.

In the Netherlands, a new spatial planning act coming into force in 2018. Through this new Environment & Planning Act (Omgevingswet), the government wants to combine and simplify the regulations for spatial projects. The aim is to make it easier to start up projects, for example, the construction of housing on former business parks, or the building of wind farms. For this purpose a central information infrastructure is needed based on clear agreements and digital standards. This is in line with the main objectives of the INSPIRE directive. Extending INSPIRE seems to be the most efficient way forward.

Geonovum has commissioned wetransform
to research and document patterns for such model extensions. Together with the INSPIRE
Maintenance and Implementation Groups, and supported by an expert group, we answer the following questions:

How can you extend INSPIRE data specifications in an uniform and standardised way?

Are we able - based on the currently best practices in Europe – to develop a standardised approach with
patterns to extend the INSPIRE data models?

Methodology

As a first step towards answering these questions, we executed a survey. We used that survey to collect best
practices, challenges and information on the created or planned model extensions.

We then describe the extension methodology. It is based on the harmonisation methodology developed in the HUMBOLDT project and then refined in more than 20 other projects afterwards. We describe different phases – Organise, Analyse, Design, Validate, Consult and Publish – and provide concrete step-by-step guidance for each of the phases.

In the tutorial, we describe different tools for modeling, transformation and publishing, such as Enterprise Architect, GeoServer, deegree and Shapechange.
